The munition may include a warhead, such as a penetrating warhead, enclosed within an air frame. The air frame may also allow connection to a standard mount, and / or a standard nose kit or tail kit. The air frame may have preformed debris therein, packed between the air frame and the warhead. The preformed debris may be loose, packed in a potting material, or may be in a flexible bag. Debris may improve the performance of munitions. The warhead may also contain preformed debris.

In the following description, a general description of a munition with a penetrating warhead is provided first, and a munition includes an air frame enclosing the warhead. Details of the preformed debris that may be located within the air frame and air frame will now be described. It should be understood that the air frame described below may be used in combination with other types of warheads (other than through-through warheads).

1-3, a munitions 10, such as a missile or guided missile, is housed within an air frame 14 having connection lugs 16 for connection to an aircraft or other platform for launching the munitions 10. [ (12). The air frame 14 includes a front connection 22 for receiving a guide nose kit 24 (for example), and a tail kit 28 for receiving a tail kit 28 having a deployable fin 30 (For example). The air frame 14 may be configured to use standard weapon mounts on a launch platform also capable of accommodating other types of weapons. The connections 22, 26 may be standard connections similar to those used for other munitions, thus enabling the use of standard nose and tail kits that may be used with other types of munitions. The air frame 14 may be in the form of a pair of clamshell halves that fit around the warhead 12 and may be made of a relatively lightweight material such as aluminum.

The warhead 12 has a perforator shell 34 for enclosing the explosive 36 therein. An asphalt liner may also be present between the perforator jacket 34 and the explosive 36. The asphalt liner serves as a sealing material and a protective layer for the explosive 36 during storage, transport and target penetration. The explosive 36 is exploded in the fuse fountain 40 by the fuse 38 at the striking end of the explosive 36. The envelope 34 has a front nose 52 and a stamper section 56 extending rearwardly from the nose 52. In the illustrated embodiment, the front nose 52 of the perforator sheath 34 is an essentially solid one-piece structure (not shown) having no cutouts or through-holes for receiving a front mounted fuse tube, such as that used in a universal bomb shell, to be. The front nose 52 is thickest at the apex 58 of the nose 52 and decreases farther rearward along the envelope 34 to provide a thickness that gradually tapers to the thickness of the substantially cylindrical star section 56 . The nose 52 may have a maximum thickness that is at least twice the thickness of the thickest portion of the shell 34 in the cylindrical star section 56.

4, the stamper section 56 has a series of reduced thickness portions 62 adjacent another portion 64 of the stamper section 56 that does not have a reduced thickness. The reduced thickness portion 62 introduces a weakened portion into the portion of the perforator sheath 34 to facilitate destruction of the sheath 34 when the explosive 36 explodes. This may improve the generation of debris from all or part of the envelope 34 when the explosive 36 is exploded, thus improving the durability of the warhead 12.

In the illustrated embodiment, the thickness reduction portion 62 is a series of holes 68 parallel to the longitudinal axis 70 of the warhead 12. The holes 68 do not intersect each other, but are distributed circumferentially around the stamper section 56. The apertures 68 may be distributed substantially evenly circumferentially about the stamper section 56, but a non-uniform distribution is a viable alternative. The use of the hole 68 to create the thickness reducing portion 62 is only a workable configuration. Alternatives such as notches or grooves on the inner and / or outer surface of stamper section 56 may also be used. These alternatives are described below.

The thickness reduction portions 62 of the illustrated embodiment are comparative shapes and are elongated with a length (in the axial or longitudinal direction) that is at least 10 times their width (in the circumferential direction), for example. Thickness reduction portion 62 may be substantially the same in length, width, and material thickness reduction, but alternatively, thickness reduction portion 62 may vary from one another in relation to one or more of these parameters.

Holes 68 may also be filled with denture enhancing material 76, further increasing the utility of warhead 12. In the illustrated embodiment, the holes 68 are filled with the preformed debris 80. The debris 80 includes two types of debris wherein the steel preformed debris 82 alternates with the zirconium tungsten preformed debris 84 and the debris 82 has a different size and shape Respectively. More broadly, debris 80 may include debris having different materials, different shapes, and / or different sizes, but as an alternative, all debris may be substantially the same in material, size, and shape. Other materials, such as spacers, may be disposed between the rigid preformed debris.

One advantage of the munitions 10 is that they provide flexibility and adaptability to debris size, weight, and shape. These parameters are adaptable according to mission requirements. For example, smaller debris such as the size of a pebble is more suitable for localized full coverage, while larger debris sizes permit more observable damage within the target site.

The debris 80 is projected outwardly from the shell 12 when the explosive 36 is exploded. Thus, the warhead 12 has the characteristics of both penetrating and non-penetrating weapons. The perforator sheath 34 remains as the warhead 12 strikes a solid target, such as a concrete building, causing the warhead to penetrate into a solid target, possibly into an interior space that may be occupied by the target person . Next, the fuse 38 detonates the explosive 36. This causes the sheath 34 to rupture with debris that can damage the solid interior of the target due to the weakened portion introduced by the thickness reducing portion 62. In addition, the preformed debris 80 may improve the fracture effect of the warhead 12.

The durability enhancing material 76 may alternatively or additionally comprise an energy material such as a chemical reaction material. For example, debris 80 may be spaced apart, with the energy material disposed between adjacent portions of the debris in hole 68. The energy material may be any of a variety of suitable explosives and / or coal, such as, for example, hydrocarbon fuels, solid propellants, propellants, spontaneously ignited metals (zirconium, aluminum or titanium), explosives, oxidants, Or may include them. The explosion of the explosive 36 may be used to trigger a reaction (such as an explosion) in the energy material located in the thickness reducing portion 62. This may add additional energy to the explosion, assist in propelling the debris 80 and / or destroying the perforator sheath 34 with debris.

A number of alternatives are possible for the type of arrangement and material. The energy material may be disposed between all adjacent pairs of debris 80, or next to all the second debris, or all third debris. In addition, the material may comprise a substance capable of neutralizing or destroying a chemical or biological agent.

The fiducials enhancement material 76 may be omitted from the hole 68 and if desired, the hole 68 is simply filled with air (e.g.) or gas, or liquid. The improved fracture of the shell 12 without fracture enhancing material 76 results from the fracture of the perforator sheath 34 to smaller debris due to the reduced thickness area of the perforator sheath 34. [

The perforator sheath 34 may be made of a suitable steel (e. G., 4340 steel) or other suitable material, such as titanium. Aluminum and composites are other possible alternatives. An example of a suitable material for the explosive 36 is PBXN-109, a polymer bonded explosive.

The hole 68 may be a through hole, or it may be a blind hole that proceeds only to a certain depth. The depth of the blind holes may all be the same, or may vary due to achieving certain desired effects, or due to system-level requirements such as various hole depths due to, for example, aircraft mounting lugs. The holes 68 may be fabricated by machining, for example, by drilling, or by other suitable processes such as acid etching. In the illustrated embodiment, the hole 68 is only in the stalk shell section 56, but alternatively there may be a hole or other thickness reduction in the portion of the nose 52.

Fig. 5 shows further details of the clam shell inclusion body or air frame 14. Fig. The inclusion body 14 includes an upper assembly 102 that includes an upper clam shell segment 106 as well as a nose ring 108 and a tailing 110. The lower clam shell piece 116 engages a portion of the upper assembly 102 to enclose the shell. Fragments 106 and 116 may be made of aluminum alloy, or other suitable material. Fragments 106 and 916 together form a series of bays (openings or cavities) for receiving debris and / or other durability enhancing materials in any of a variety of forms. The upper clam shell segment 106 has upper bay portions 122, 124, 126 and 128 and the lower clam shell segment 116 has lower bay portions 132, 134, 136 and 138 ).

The puncture may be improved by providing a shredding pack within the pockets or openings in the air frame or enclosure 14, such as the bay portions 122-138. The shredding pack 190 may be an encapsulated package that contains debris and possibly other durability enhancing materials such as explosives, as shown in FIG. 8, described below. The debris enclosed within the pack may be similar in material and other aspects to the various debris 80 (FIG. 4) described above. Additional materials in the shredding pack may include any of the other durability enhancing materials 76 (FIG. 4) described above, such as energy materials. The shredding pack enclosure for the shredding pack may comprise any of a variety of suitable materials, such as suitable metal and / or plastic materials. The shredding pack may be deformable to assist in the placement of the shredding pack in the pocket. The shredding packs may all be substantially identical, or there may be different sizes and / or shapes for the shredding pack to be placed in different pockets formed by the bay portions of the clamshell fragments.

As an alternative to (or in addition to) the shredding packs, the shards may be arranged in different ways in the openings or pockets to increase the durability. The unpackaged debris may, for example, be disposed within the opening with a potting material or cover to hold the debris in the opening. The debris disposed within the opening may be similar to the debris in the debris pack, as described above. In addition, other durability enhancing materials such as those described above may also be packed in the openings.

Figs. 6A and 6B show one such alternative casting debris block 142. Fig. The block 142 may be cast into a shape that fits within one of the bay portions 122 to 138 (Figure 5). The mold may be manufactured corresponding to the shape of the bay part to be filled, and the different bay parts have different molds (with different shapes). The mold may then be filled with a mixture comprising one or more of the various types of debris described elsewhere herein. The mixture may comprise debris (e.g., two sizes of steel shots, heavy shots, tungsten alloy debris, more broadly, a plurality of sizes, shapes, and / or fragments of material) having a binder material. Examples of suitable binder materials include, but are not limited to, EPOCAST (injectable epoxy resin materials) and CLEAR FLEX (urethane based materials), epoxy based binders, or energy binder materials such as aluminum-polytetrafluoroethylene (PTFE sold under the trade name TEFLON ) Based materials). Other materials may also be included in the admixture, such as an alkaline or pyrophoric material. One desirable characteristic of the binder material is that it does not excessively inhibit the separation or singulation of debris when the explosive in the munitions explodes.

Figure 6a shows the fragment block 142 after it has been removed from the mold. Block 142 may then be placed in a suitable bay such as bay 118 shown in FIG. 6B. The block 142 may be adhesively secured within the bay portion 118 with a suitable adhesive. Alternatively or additionally, the block 142 may be at least partially mechanically secured within the bay portion 118 secured by, for example, a strap 144, as shown in FIG. 6B. Other types of mechanical fixtures may be used instead of, or in addition to, such as sheet metal plates that cross the block 142 to hold the block 142 within the bay portion 118, for example.

The composition of the cast shatter block, such as cast shatter block 142, may be varied to achieve different effects. The amount of debris or debris of a different type may be used to achieve different weights. In addition, differences in size and / or type of debris may produce different shatter effects.

7A and 7B illustrate an alternative embodiment of the present invention as a debris block or debris (or loose debris or potting) within a debris block 80 or a debris block disposed within bay portions 122 through 138 (FIG. 5) ≪ / RTI > broken pieces). 7A shows a cartridge 150 that includes an envelope 152 and a series of small fragments 154 (spheres in the illustrated embodiment) within the envelope 152. As shown in FIG. Small debris 154 may have a number of alternative shapes, such as cubes and / or thin cylinders and / or other shapes. A cut material such as a spontaneous ignition material is housed in the cylindrical cartridge. The envelope 152 may have various lengths and / or diameters.

Fig. 7B shows an example of the star-shaped debris 160. Fig. The star shaped debris 160 has a flat body 162 having a series of flutes 164 creating edge-like protrusions 166. When discharged from a munition, such as the munitions 10, the star-shaped debris 160 may be spun during flight, allowing stable flight over significant distances. The edge-shaped protrusions 166 may facilitate the star-shaped debris 160 to penetrate the object they strike. The protrusion 166 may also rupture or otherwise dislodge the cartridge envelope such as the envelope 152 (Figure 7a) of the cartridge 150 (Figure 7a) to release the debris 154 (Figure 7a) It may also be helpful to open it in a way. The protrusions 166 may have any of a variety of suitable shapes having a barbed shape that facilitates, for example, penetration and disruption of an object to which the star-shaped debris 160 strikes. In the illustrated embodiment, the debris 160 has six protrusions 166, but a flat piece with a different number of protrusions is alternatively possible. Star shaped debris 160 may be made of a material similar to that of other debris described herein.

Figs. 8 to 10 show a process of charging the bay portion which is one of the bay portions 122 to 138 (Fig. 5). In Fig. 8, the debris 180 is bonded to the inner surface of one of the clamshell fragments in the bay portion 118. The debris may be a spherical debris such as a reactive metal-coated metal alloy ball, or it may be bonded to a clamshell piece using a polysulfide or polysulfide compound.

In Fig. 9, a bag or pack 190 of material is disposed on top of the layer of debris 180 shown in Fig. The pack 190 shown in FIG. 9 is an example of a shredding pack described above. The pack 190 of Fig. 9 is a plastic bag that encloses the durability enhancing material. The pack may contain a metal powder material, such as aluminum, magnesium, zirconium, titanium or other reactive material, which may be densified, for example, in a suitable binder material to provide a soot or bag providing improved blowing effect. The bag may also include one or more bags that contain solid debris, such as spherical debris made from reactive material coated steel or tungsten alloy balls, or other suitable solid material, for example.

In Fig. 10, the bay is sealed to keep the debris and the pack (bag) in place. The bays may be sealed by a solid material, such as sheet 194 of aluminum. The solid material shell may be joined to the clamshell piece and / or pack with polysulfide (or other suitable adhesive), and then mechanically fastened to hold it in place by, for example, a series of screws or bolts.

The configurations and methods shown in Figures 8-10 are only one example of a possible configuration. Numerous alternative configurations and materials are possible, some of which are described elsewhere herein.

11-13 illustrate the use of munitions 10 in the target penetration mode. In Fig. 11, the munitions 10 are shown as approaching the rigid target 200. Fig. 12 shows a munitions 10 colliding with a hard target 200. Fig. It is possible for the warhead 12 to penetrate the rigid target 200 to reach the inner region 202 of the rigid target 200 along with the perforator sheath 34 thereof. Other parts of the munitions, such as the air frame 14, the nose kit 24, and the tail kit 28, are broken and / or separated from the warhead 12 by collision with a rigid target 200.

Fig. 13 shows the crushing effect of the warhead 12 after penetration. The figure shows the situation after the explosive 36 is exploded. The debris 210 is diffused within the hard target interior region 202 by the explosion. The debris 210 includes debris produced by the breakage of the through sheath 34 and possibly other preformed debris that has been placed in the aperture 68 in the envelope 34. [ The debris between the envelope 34 and the air frame 14 (FIG. 2) may also be part of the debris 210.

Figures 14 and 15 illustrate the use of munitions 10 as breakage weapons without penetration. Figure 14 shows the munitions 10 in a steep dive approaching the desired explosion position 220 on the ground 222. The fins 38 (FIG. 3) may be set to provide an explosion at a desired height, and different heights may be used for different types of engagements (different types of soft targets, spread over different areas). By way of example, the desired explosion position 220 may be 3 to 4 meters above ground 222, but a wide range of other explosive heights is possible.

FIG. 15 shows an explosion at location 220. FIG. The explosion diffuses the debris 126 around the area near the explosion location 220. 13, the debris 126 is formed between the perforations 34 (Fig. 3), preformed debris 80 (Fig. 4), and between the envelope 34 and air frame 14 It may also contain fragments of debris. The fracture mode shown in Figs. 14 and 15 may be useful for attacking a smooth target diffusing to a certain extent, such as an exposed enemy.

The improved crushing provided by the munitions 10 is achieved by the use of the fins 38 to control whether the explosion occurs at a height above ground or after the penetration of only the hard targets, It may also allow for good flexibility in engaging, as well as using a single munition in multiple modes. The choice of target (hard versus soft mode, fuse delay, and / or height of burst control settings) can be achieved in any of a number of ways: 1) by a pre-set by ground crew before launching a weapon for some systems, 2) Or controlled from an aircraft or other launcher before launching the weapon by means of a ground control or pilot for the system, and / or 3) controlled after the launch of the weapon via the data link.
